Properties of the telephone interview for cognitive status: Application in epidemiological and longitudinal studies


Journal Article

We evaluated the utility of telephone screening for dementia in epidemiologic research by comparing performance on the modified Telephone Interview for Cognitive Status (TICS-m) with results from in-person neuropsychological measures in 67 elderly males. Longitudinal performance on the TICS-m was also evaluated over an average of 15 months in the same subjects. After comprehensive clinical evaluation, subjects were assigned to one of three diagnostic groups: normal, demented, or "mild-ambiguous" cognitive syndrome. As expected, the normal group scored highest on the TICS-m, followed in turn by the mild-ambiguous and demented groups. Among various neuropsychological measures, the Mini-Mental State Examination correlated most strongly with the TICS-m. The scores on the first and second administration of the TICS-m were significantly correlated for both the normal and demented groups. The normal and mild-ambiguous groups showed slight improvement on the second administration of the TICS-m, but the demented group showed a slight decline in their scores. Thus, the TICS-m is able to detect dementia and decline in cognitive function over time, and therefore appears useful for population studies as an economical alternative to standard in-person screening. © 1994 Raven Press, Ltd., New York.
